Leicester City head coach Marti Cifuentes told BBC Radio Leicester:
"We had a very good first half with a lot of good moments, a lot of good sequences of play.
"We were very dominant, we had something like 12 shots and conceded only one.
"We spoke at half-time about the need of scoring one or two more goals because it doesn't matter how dominant you are in the Championship, the games can shift quick.
"The second half was not good. We tried to play too much centrally, we had some turnovers, we conceded some counter attacks and the goal was exactly like this.
"We had this attitude that I like to chase until the end and we had these couple of good chances but we need to accept that the second half was not at the level we expected."
Portsmouth manager John Mousinho told BBC Radio Solent:
"It feels like we could have had all three points, I thought we had the better chances to win it.
"You come to the King Power and take the point. I'm really happy with the performance, I think we need to be more ruthless going forward.
"We could have had more confidence and belief in ourselves.
"My message at half-time was let's not get done by those silly mistakes and we did that. In the second half we were on the front foot and were confident.
"John Swift has been one of those who has grown into the season, we want to play him higher up as he can score goals.
"He came into the game more in the second half, I thought it was a really good goal."
